To all whom it may concern:

Be it known that I, Wrnmsn O. F. Mrermn, a citizen of the United States, residing at Waldo, in the count of Marion and State of Ohio, have invented certain new and useful Im rovements in Ice-Cuttin Machines, of which the followi is a spe cation.

My invention re ates to ice cutting machines, and has for its object the revision of a device of this character provided with a plurality of saws, one of said saws cutting" the ice into longitudinal strips, another o said saws cutting said strips into blocks and a third saw cutting a guide groove in the ice to guide the machine in its succeeding trip across the ice. 7

A further object of the invention is the pro vision of im 'roved means for automaticafter a predetermine movement until t e block cutting saw has completed the cutting of a bloc from the strip and also of improved means movement u pen the 'shaft.

This shaft carries for bodily elevating the machine at the end of a trip) to facilitate its movement'to a position to egin the next cut.

Further ob'ects and advantages of the in? vention will e set forth in the detailed description which now follows.

In the accomfpanying drawin st Figure 1 is a plan view 0 the machine, 2 is a side elevation, Fig. 3 is an end elevation, F 4 is a section on llne4-'-*w of 1,.looking1ri the direction of the arrow, Fig. 5 is a detail view of the drivin means or an automatic stop wheel, and, I i 6 is a view showing means for 110' saw 'that cuts the ice into .'atany etermiiied height.

Li e numerals designate corresponding part in all tr the figures of the drawing.

In the drawing, the numeral 1 designates a framework which is adapted to rest upon the ice and which; supports agasolenc engine 2, the side members of the frame serving as runners in the movement of the machine. Upon one end of ill) framework are located blocks 3 which support a shaft 4. 5 ands. zavin a swm 1n M iuntcd in th the arms 5 is a second shaft 7.

pulley 6, said arms. 5

outer ends 0 u pon' pile and the large circular saw 8 and upon its opposite end the smaller circular saw 9. The circular saw 8 is designed to saw the ice into strips and the small saw 9 is designed to saw a groove in the surface'of theice so that the machine in making the next cut will be guided by this groove. A small pulley 10 is also mountedupon the, shaft 7 and is connected with the large ulle B by means of a belt 11. Con necte wit the shaft 4 by means of a pull 12 is a belt 13 which connects with the pu 1e 14 of the gasolene engine. Upon one end 0 the shaft 4 is a bevel pinion 15. This pinion engages with a pinion 16 whichis mounted upon a shaft 17 (see Figs. 1 and 3)." This shaft 17 is mounted in bearing blocks '18 and u )on the shaft 17 arms 19 are mount- Upon the crank shaft which in this case is made long and is sup orted' by a bearing 26 upon an inclined caring arm 27, is

pulley has upon its inner side next to the motor a groove in which a belt 29 is adapted to run. A second friction ulley 30 is 16- cated behind the first named friction ulley and is similar in construction. A thir mounted a friction pulley 28. This friction fries tion pulley 31 is mounted betweenthe pulleys 28 and 30' and is adapted to be forced into frictional engagement with either the ulley 28 or the pu ley 30. The friction uley 31 is mounted upon a shaft 32, whic 1 at;

one end is mounted m a bearing 33, the outer end of the shaft being1 supported in a mov t to able bearing 34, and

caring 33 permits ting a slight lateral movement-of shaftf32:

This movable bearing 34 comprises a support 35 which is pivoted as at 36 to the arm 27." To one end of the beari support 35 is con:- nccted a link 37; this bar cing pivoted to the handle or controlling lever 38. The lever 38 3 is in turn ivoted at 39 u on an upright 0st 40.

ey 31 either into en It wt 1 thus be seen t at if the hand e 38 is moved either to the ri ht or to thelelt, it vwill force the friction gagement with the friction pulleyZS or friction pulley 30 thereby causing the shaft 32' to revolve either in one direction or in the other; j

In order to transmit motion tot-he entire machine, a bevel pinion 41 is securely fastened to the shaft 32 and mesheswith asec- Jill shorter than the others. .makin these teeth shorter is this: Assume 0nd bevel pinion 42 mounted u'pon a shaft 43. A worm 44 is fixedly mounted upon one end of shaft 43. This worm in turn meshes with a worm wheel 45 which is mounted upon a shaft 46 carrying upon its extreme end a sprocket. wheel 47, said sprocket wheel 47 being connected with a second sprocket whee 48 h means of a chain 49. The sprocket whee 48 is mounted upon a shaft 50, upon which shaft is mounted a roller 51 having a number of spikes or teeth 52 securely fastened thereto. These teeth are to pro ect into the ice to propel the machine forward or backward. A foot lever 53 is pivoted near one end, as at 54, and is ivotally connected with a yoke bar 55, w iich is more clearly shown in Fig. 5 of the drawing. This foot lever 53 is for the purpose of ra1sing the worm wheel 45 into engagement with the worm 44.

By referring to Fi 5, it will be seen that two of the teeth 0 the worm wheel are The reason for that a )lock of ice is to be cut from the strip and the machine is stopped so that the cutoff saw 21 may be lowered to cut 011' the desired bloc-k. After this has been done, it is desired to move the machine forward just far enough to cut oil' a second block. In most cases, blocks of ice are cut about 20 inches square, therefore it will be seen that the entire uni-chine must move forward just 20 inches and stop. In order to do this the foot lever 53 is pressed at one end, which forces the worm wheel 45 up so that the short teeth will become engaged with the worm wheel 44. Just assoon as these teeth enage the worm, the machine starts to travel forward. Assoon as the machine gets under way, or has traveled a few, inches, the foot lever 53 is released so that the worm wheel 45 drops to its original position, but by this tune the long teeth are in engagement with the wflllllyfifl that the travel of the machine engagement with the worm wheel 45 and the.

machine is automatically brought to a stop to Jll'llllL the cutting off of another block.

n order to raise. and lower the cut-off saw 21, a second lever 56 is used, this lever bein pivoted to the post 40 as at 57.. Connecte to the lower end of the lever 56 is a link 58, the opposite end of which is connected to one of the arms 19. it will be seen that by ra'ising upon the handle of the lever 56, the cutoll' saw 2] will be lowered, therefore sawing into the block of ice and cutting it free from the main strip. A seat 59 is provided for the operator, who rides upon the machine.

in order to kee the machine from getting out of the desire position in moving across the ice, the saw 9 cuts a groove and upon the bodily elevating the machine.

frameworkof the machine I have provided, at its forward end, a guide plate 60 and at the rear end asimilar guide plate 61. In order to set the circular saw 8, so that it will out only to a desired depth, I have provided upon each side of the arms 5 a lag screw. This screw extends into the arm for only a small distance and upon the bearing post 3 is a lug 62. A circular arm 63 is pivoted in the lug 62 and upon each side of the arm 5. A rod 64 connects the two circular pieces63 at their upper ends. U on one face of the segment 63 are a num er of notches 65. These notches engage with the lag screws and hold the arms in the desired osition. Xow, in order to set the saw at an i e evation, a rope or cord 66 is connected with one of the arms 5 as is shown in Figs. 1 and 4 of the drawing. This rope extends downward from the arm 5 through a small pulley located upon the framework and from there up to the seat post. In order tO-set the saw, it is necessary to grasp this rope and ull up upon it and at the same time lean orward and throw the arms 64 back out of engagement with the lag screws and then raise or lowertlie saw, allowing the arm 63 to come back to its original position and engage the lag screws withv the notches 65.

n order to move the saw or machine after the machine has completed a cut across the ice, 1 have provided near its forward and rear ends, better shown in Fig. 2, a means for These means comprise blocks of wood 6? half the thickness of the frame, which are connected with the frame beams by the links 68 (see Fig. 4).

'Ncar the center of the frame and the bar, are

la screws 68 which extend into the wood on ly a short dsitance. A lever 69 which has one end bent is adapted to pass over the lag screws ill-such manner that when a down ward pull is exerted upon the lever 69, it will cause the bars 67 tobe forced downward, and raising the machine up off of the ice by bringing the links to a substantially vertical position. These bars 67 will be forced back against the side frame, so that the links 68 will he a little beyond their centers. There will, therefore, he no danger of the machine running until after the bars 67 have been returncd to their i-iriginalposition. 46 upon which the worm wheel 45 is mounted, as is shown in Fig. 2 of the drawing, has an elongated bearing. This is to permit said shaft to be forced up until the short teeth on the worm wheel 45 mesh with the worm 44. It is also to be understood that. the bearing 33 must be so constructed as to allow a little side movement, so that in forcing the friction disk 31 against either of the friction disks 28 or 30, it willnot bind.

The operation of the device is as follows: The gasolene engine having been set in operation, the foot lever 53 is depressed an the The shaft
